How Can I define rigid plane?
[Final Edit now I think I understand the problem better]

OK, so I have the same behavior as you if I use your AN setup. Blender expects the passive to not be moving, or you to be explicit about it if it's moving.

So my solution:

Select cube, go to physics, add rigid body, select type active.
Select plane, go to physics, add rigid body, select type passive. Under settings, tick Animated.
Play animation.

It should work.
